METHOD FOR THE PUTTING TOGETHER OF THE METAL WIRES IN SHAPES FOR LADIESHATS.

Specification 01' Letters Patent.

Patented Dec. 26, 1911.

To all whom it may concern:

Be it known that I, J OHAN CHRIs'roFrER BARTZ, citizen of the Kingdom ofDenmark, and a resident of Hostrupsvej 10, Copenhagen, Denmark,electrician, have invented new and useful Improvements in Methods forthe Putting Together of the Metal Wires in Shapes for Ladies Hats, ofwhich the following is a specification.

The ladies hats now in use consist, as a rule, of a metal wire shape,which, in the majority of cases is covered with cotton or metal threadsor plaited or twisted together, the vertical stiffeners being twisted ina knot around the horizontal ones or vice versa. This method ofprocedure is a very detailed one, and as a consequence expensive, notleast on account of the fact that it cannot be done by machinery. Thenit must be added that the wires easily get out of place in relation toone another, whereby the shape loses its original form. Furthermore, itshould be remarked that the wires are easily affected by damp and rust,so that they destroy the material of which the hat is made.

My invention treats of putting together the wires by welding, which isconsiderably more expeditious and much cheaper.

The welding itself is done by the wellknown autogenous process, but thisdoes not, however, constitute a part of my invention.

The characteristic feature of the invention consists in placing thewires together crossing each other, upon a firm metal foundation.Through the subsequent heating caused by the welding, the wire lyingCopies of this patent may be obtained on top sinks down on both sides ofthe underneath one, on account of the softening of the metal produced bythe heating. By this means all the wires on all sides around the placeswhere they are to be brought together will lie in the same plane.

The invention is shown on the accompanying drawing which shows a portionof the shape for a ladys hat, seen from above.

1 are the bent steel wires and 2 the radial wires.

It will be seen from the drawing that the radial wires 2 overlap thebent wires, but because of welding against a firm foundation, the wire 1on both sides of each stiffener is sunk into the same plane. By thismethod of procedure, covered wires cannot be used, and the shape,therefore, can be conveniently coated with one or other suitablecoating.

What I claim, and desire to secure by Letters Patent, is:

The method for securing together the metal wires in shapes for ladieshats, consisting in placing the wires upon a firm foundation with thewires crossing each other, and then applying the welding heat at thecrossing, thus causing the top wire to sink at each side of the crossingpoint to the same plane as the lower one.

Signed by me at Copenhagen, Denmark, this 18th day of April, 1911.
